I 'My invention relates to that class of harvesting machines which are known as combined reapers and mowers and it consists, first, inthe manner ofconnecting the cutting apparatus tothe axis ofthe cutters crank-shat`t; second, in the manner of constructing theframe which carries the bearing-wheels, so that said wheels may be adjusted vertically in` regard to the mainframe, without the use of sector standards; third, in the manner of' mounting the driversseat, so asto he independent of the main fra-me of the machine; fourth, in the manner of constructing and connecting the'cutters driving-pitman fifth, in themen-ner of constructing and `combining the reel and rake-head with the'required guides,so that Ythe rake may be raised up independent of' the reel topass over the grain .upon'the platform, ivhen desired.

That others may'undcrstand my invention, I utili particularly describcit.

A` is the main frame of my machinenupon which is mounted the main driving-pinion,shaft'13,- the cutter's,V

drivingcrank 'shaft' C, and the reels-driving-pinion shaft D. The tongueE is connected to the-front .end of the main frameiby a flexible connection, but may be rendered rigid at any desired point-of elevation by the strap F`through one of se series of holes, in which a pin, G, is thrust into a ho'le in thefront edge of the drivers'footyhoard II, which' is mounted upon the mainframe and is supported by the legs I. -The bearing-wheels pinions ,I Jmay be'thrownrout of gear independent of each otherbyclutches K, and themain heveldrvirig-gear Lmay be thrown in andout of gear, as` desired, by means ot" a'clutch upon the main driving-pinion shaft B. TheseY features are not peculiar to this invention, and are not, in detail, essential to it. They are shownand ailuded lto merel'yfor'the purposeofrendering the operation and constructionoi' those devices,to be hereafter described,

completely understood. Y J y A When the machine is arranged for reaping it-is required that the cutting apparatus should-be supported at a certain Cif-stance above the surface ot'` the ground, and'this is accomplished by placing under oneend a. grainwheei, and supporting the other end by itsattachment to the main frame, while in mowingrthe cutting apparatus ispemitted to slide upon the ground,-risin`g and falling to conform to the undulations thereof, independent' of the t'nali'n frame, and th'etwo ends independent oi` each .,other. LIn the first case it .becomes necessary that the connecting-arm M (which hasone of its ends centred upon the-axis of the cutter-"s crank-shaft C, and the other -end centred upon -heaxisrof the dra'gbar N,) should be renderedrigid, by securing one o'f its ends in a certain position, as' regards the main frame or cutting apparatus. Ifpreier to secure it` to the cutting apparatus, as securing the moet nearly perfect result. I therefore use the brace O, which I' secure by screws or bolts to the arm M,'at ornear its. centre of length', and to theshoe'l', at the inner end of the cutting apparatus. The bra-ce O is provided 4with a seriesot' holes neaoncof its ends, so that its effective length may be increased or diminished, as it is desiredto'support thisend of thecutting-apparstus' at a greater or less distance from. the ground. l That endof .the artn M which isfcentredfupon'the ass'of the cranlrgshaft C has its bearing upon a hub, which i forms a partof the box in which said crank-shaft revolves, and it is secured in place upon said bearings hy a hooking-Hangs, Q, which projects over it from some convenient part of the4 adjacent frame. By reference to lig. 3 it will 'beseenthat the eect of this arrangement will be, thecutting apparatus is secured to the main.

frame by a rigidlarrn, which is centred and moves upon the axis ofthe crank-shaft C, so that this end of the cutting apparatus must-always be'snpported at the mean elevation of the main frame, while the -two `bearing-wheels of the machine may rise-and fall withth'e u'ndulations'of the ground-over which they are passing, causing the main frame to change its horizontalityfwithout changing materially the elevation f the cutting apparatus, because during such movements of the main frame, it maybe supposed, andwill, in fact, move in relation to the cutting apparatus upon theLshaft-C as acentre, and therefore will not necessarily disturb the position of the arm M.

When the machine" is iused for mowing the brace O is removed and the shoe P permitted to rest upon the ground. The connection of the cutting apparatus and the arm M is Athen dexiblc, so that the outer end of said apparatus may rise and fall, moving upon the axis of the drag-bar N as a centre, andthe shoe 1 may rise-and fall, moving the arm M upon its bearings at each end, and being maintained always at the same distance from the crank-shaft '0, so that the position of the strokeof the c'utter is unchanged-in any event. I'

Tlie'bearing and driving-wheels R R-are not attached to thc. main frame A directly, but are set upon two i parallel plates SS, which are centred upon the axis of the main' drivingpinion 'shaft B, so thatas the axis of the wheel- R'changes its relative position to the main frame, the distance between said axis and the'axis of the pinion-shaft B shall not be varied,and the pinions J will not be disconnected fromtheir driving-gea-rson the wheels'Rl. It 'is of coursenecessar'y, when using th'e 'coupling-arms or'plates S, to so guard their movements that they shall not changetheir parallelism in any material degree, and this has hitherto been accomplished by providing a curyed standard, upon which the edge of the 'coupling-plate should move` and be secured from any other than the proper movement, by a groovcd flange, orv its equivalent, which should secure the plate to vthe standard. I have accomplished the desiredrcsult by 'attaching` the two plates S S, not to standards, but to each other, by vthe cross-bars T U, which insure the continual parallelism of the two plates, and by the interpositiou of the main frame, which fills the spacebetween them, they are prevented from moving laterally out of place. Thus the frame A may move up and down, in respect to the bearing-wheels and independent of. the frame S, andwithout'disturbing the connection of the driving-wheels withtheir pinions J. I

The cross-bar T is not rigidly secured to the plates S. It is providedfwith cylindricaltangs at eachend,

which pass through holes in the plates S, and are secured by nuts o'n the outsides of .said plates. These tangs also act as journals' upon which the bar T may turn.' This movement of T is limited, however, by a pin, which projects from gthe-ond of the bar through a curved slot, V, and is designed only to be sudic'ient to permit the upper'snrfaceof the crossabar to remain always parallel with the upper surface of the main frame. This pary.allelism is rendered necessary. .by placing the drivers scat W 'upon this cross-bar, where it iis-at all times in "the,

same position respecting the axle of the driving-wheels. In order to secure the properposition of the cross-bar TI bolt to the upper side of it the arm'X,-which.tl1ence passes forward beside the edge of the drivers foot-board,

Aand through the eye Y, which is attached to the frontbar of the main frame, and thereby retain the cross-bm'- T in about the same position to the surface of the main frame. The standard et is erected upon the mainframe and passes through a slot inthe cross-bar T. It is provided with a series ofgholes, through oneof which a pin may be thrust to connect it to the cross-bar T, or it may be secured by sime other convenient means; the object being to hold the cross-bar Tpland main frame A in any determined position in respect to each other.

v The drivers seat W being inounted'upon the frame which connects the wheels, is independentV ofthe-movements of the main frame, and the movements of the latter are not a'ected by the weight'of the driver. vIn

reaping, the seat is thrown forward as in tig. 2, when the weight of the driver will counterbalan'ce vthe weight of theplatform and cutting apparatus; but in mowing, the position is reversed, the standard being-turned about so as to bring the weight of the driver in rear of the axle s of the main wheels R, and thus countebalance the v,weight of the forward portion of the machine, and keeping the cutting apparatus down upon tv he ground.

The pitm'an j is connected to the crank-wheel b by the head c, thi'ough which the wrist-pin passesgmd the ball-,and-socket'joint-cl, so that ,the side strain upon the wrist-pin and unequal weanmay be obviated as A'much as possible. At theA other end of the pitman the joint is formed by inserting the end .between two lugs formed on the end of the cutter-bar, -and passing a conicalbolt, e, through a 'suitable hole formed in the lugs andipitman end. '-This boltis kept in place by the gu'idcj', which'covers that endfof the sickle-bar and retains it alwaysinproperdin'e of working. It'is adjusted 'by the screw g, which. projects from its larger end, and when in proper position alwaysslides along against the inner surface of the gui'de'f.4 The set-nut fprevents any shifting of the adjusting-screw,t vThis method of construction permits the pitman to be uncoupled fom'the cutter-bar without the removal of any nuts or screws, as it isonly necessary to withdraw theY cutter from thel -guide-wayfar enough to clear the head and bolt e from the guidef. The spring-latch'prevents any accidental withdrawal of'thehead of the cutter far enough to permitithe bolt e to become displaced; indeed, the cutter cannot be withdrawn far enough for that purposel except by uncoupling` the pitmantat thecrank, or b'y raising the outer end of the cutting apparatus'so that the cutter-bar is nearly vertical.

y The rake and reel. are driven by'gearing throughout, and receive motion-from the main driving-pinion. shaft B, by means of the countershaftD and the jointed shaft le. As theV cutting apparatus may be raised or lowered without disturbing the position of the mainframe, it is of course necessary-that the drag-bar N and the shaft c should be so far flexible as to permit this change of position withoutpaifecting their operation. .f The drag-bar N is therefore connected to the front bar fof the main frame by a ball-and-socketjoint, and vthe shaft 'c is jointed with a universal joint, l, the frontportion being secured in position and proper lineiby the box/nt,

which is bolted to the front cross-barof the main frame. Thereis also liability of a slight end motion in backing or starting the machine when the cutting apparatus is alternately thrown forward or backward againstjts supports. This end motion, if uncompensated', would interfere with the working and connectionsof the-gearing which drives the rake andreel. I therefore cut the shaft lc, and rigidly secure one oftle cut' ends within the' :sleeve "n, while'thel'other cutend' is permitted a .limited movement b aclc and forth within said sleeve.A This moyementis limited by a pin, o',-whichpassesfthroughthe shaft, andjliesfvwithin the vslot p in the sleeve. Theifear portionof theshaft k'passes through hothzof 4the lugsor' u pturned eplshof 'the sho'e Pgla-nd-hun 'its hearings therein.` -At-a propernpo'iut within thespace between 'these bearings 'I place'- the hevel'egeang, which ltransmits the motion of the shaft 7c to the'reel and rake-shaft 4*.

The haftnfwhichcarries the -reel' and the rake,`is mounted in"and` supphrted by the hollowl standard c, l

` Awhichis securely bolted to the har t, one end of whchis tt'ed by' aten'onyinto a mortise4 in the upper endr of one of `the lugs of the shoe P, while the other endis fitted to the top'of the other'llug of the said shoe, and lsecured'therebya screwsbolt -or equixfalent means. Theshaft t and itsfrhevel-geag'which vliieshes with the gear q, projects below the barft, but is not connected to any other part ofthe frame 'ofthe machine, so that .when u the screw is removed which secures the said barV to the top of the lug of the shoe P, -the entire reh'rake. and

' their attachmentsmay h'eremoved from the machine, rthus materially facilitating the' operation of-transforming the'reaper into a mowing machine. f l p l The` hollow shaft v is secured upon thetap or upper side of the har t by screwspr equivalent contrivunces. Upon thefouter side of-the shaft 'v is the stop s, whichris secured in position by theserews-u u, and. may be adjusted up orzdpwn, as may he' necessary toV regulate "the -movemeut'oi'- the rake. The rake-guide w slidesup-zand down-freely upon the' shaft 1), hut is prevented from moving laterally thereon by the piny, which projects into a slot in the shaftf'vfor .that purpose. The reel-guide :u is secured rigidly to the `upper end of the.

shafte.4 v Y l The driving-shaft r passes upward through the standard or shaft 1) into the rake and reelhead A', to which therrnlce andreel-arm's F' arev hinged,I so thnththey` are compelled to revolve when the shaft r' revolves, but are at liberty to,rise and fall vertically, moving uponthehinge joints by which they are connected to the head A', `in-obculiene to the conformation ofthe Aguides 'w and x, which 'are so shaped that while the rake or reel-arms areV passingoverthe platform', they will move in 'a direction about parallel with said platform, and will then suddenly riseup to a position nearly lvertical, tolpassahove the main frame at as greata. distanceas possible, descending'again rapidly tostrike into the grain standing in front ot" the cutters. Thelrigers B are secured to the'lower side of each reel-arm, and-f curving downward, rest upon the `top and outer; edge of the guide x, i 'whilethe springs G prevent Yso mueh'movement of the reel or rake-arms as will throw them past a perpendicular, l

and'preventl their return toward the platform at the proper time. The 'rake is supported -aboveits guide by the `pendent arm. D', which is'pvoted to the rake-arm, andinas at its lower end airiction-roller to travel on the edge of the guide fw.

Itis sometimes necessary to. elevate the rake as it passes over the platform, so that it shall not remove the grain. `This occurs when the grain is very thin; and a suiiicient quantity fora gayel is not secured at one revolution of the rake.. In this machine I'clevatethe rake-when desired by means Yof the lever E', which raises the guide w and the rake suiiiciently far above the `platform to avoid removing any 'grain which may be upon it.

The construction and arrangement of the coupling-arm Mv,'the brace O, 'or its equivalent, in connection i with the inner shoeof a harvester cutting apparatus,.and the cutter"s crank-shaft,.solthat the cutting apparatus I substantially as and for, the purpose set forth.
